First you have to use absolute temperature (kelvin)
Then think about what the answer should be.

You are increasing the volume of the gas so the molecules ar emore spread out. In order for them to have the same pressure, ie hit the walls as hard and as often, they must have more energy - so the temperature must be higher.

You are increasing the volume by around 5% so the absolute temperature should be around 5% higher. Now you can put the numbers into the calculator!
